摘　　要：水驱前缘测试技术通过监测微地震震源位置,以确定监测井的水驱前缘、注水波及范围和优势水驱方向。薄层油藏存在的主要问题是平面矛盾,通过对比分析水驱前缘测试结果,可以判断区块注水见效情况,结合油井的产量变化,可确定需要调驱的井组,从而提高调驱措施有效率和准确率。该技术在薄层油藏C631块进行了应用,取得了明显的增产效果。Through monitoring the location of the microseismic source,the waterflooding front test technology is used to determine the waterflood front,water injection sweep range,and dominant waterflood direction of monitoring wells.The main problem in thin reservoirs is a contradiction on the plane.Based on comparing and analyzing the test results of the waterflooding front,it can be judged the effectiveness of the block water injection.And then combined with the production changes of the oil wells,it is determined the well group that needs profile control,thereby improving the efficiency and accuracy of profile control and flooding measures.The technology has been applied in the C631 block of thin-layered oil reservoirs and has achieved significant production increase effects.
